A Breakthrough development in an Indo-Japan joint research project for the

treatment of Acute Liver Failure

Nichi-In
Centre for Regenerative Medicine (NCRM),
an Indo-Japan joint venture institute based at Chennai and Centre for
Liver Research and Diagnosis, (CLRD) Owaisi Hospital, Hyderabad have
jointly developed a novel method for treating acute liver failure, which
was presented yesterday in the 4th Annual meeting of the
International Society for Stem Cells Research (http://www.isscr.org)
held at Toronto, Canada by Dr. C.M. Habibullah of CLRD and Dr Samuel JK
Abraham of NCRM. In their joint research which formally started last
year, it has been revealed that acute liver failure can be treated much
effectively using hepatocytes encapsulated in a Thermoreversible Gelation
Polymer. The Thermogelation Polymer based Cell culture technology
developed by Prof. Yuichi Mori and Dr Hiroshi Yoshioka (Professor and
associate professor respectively in polymer sciences, Waseda University,
Tokyo, Japan and also Scientific advisors & technical collaborators to
NCRM) has been applied in this research.

Acute
Liver Failure (ALF) affect thousands of patients in India every year. Major cause of ALF in India is Viral
infection. There has been no definitive treatment available for
such conditions except (i) A temporary rescue procedure such as
Extracorporeal liver support called as MARS (Molecular Absorbent
Recirculatory System) which is available only in a handful of centers
in the country and (ii) Orthotopic liver transplantation, which is a
highly technically demanding and expensive treatment, again performed only
in a handful of centers in India, with a success rate of 60%. Dr
C.M.Habibullah`s research team had earlier come out with a new idea of
using the foetal liver (Taken from aborted fetuses with informed
consent after approval by the ethics committee) in treating the
diseases with successful outcome, though the foetal cells last only for a
couple of days inside the body. But due to shortage of the foetal liver,
this treatment has its own limitation. Now with this novel approach of
using TGP encapsulated hepatocytes we have overcome those obstacle. We
have proven that the expansion of the foetal liver substance in vitro (In
the laboratory) and prolonging its life and functional capability in vivo
(Inside the body) is possible using our technology in animal models. When this same principle can be applied to patients, this could save
thousands of patients in India who suffer from Acute Liver Failure, if
they come to the hospital early.

First
time in the world:

This is
the first time in the world that a non biological (Totally synthetic)
material has been used as a substrate developed Prof. Mori et al., of
Waseda University, Japan, to grow (cultivate) human foetal hepatic cells,
cell lines and tissues including stem cells thereby paving a way for
avoiding biological materials for this purpose and avoiding viral and
other dangerous known and unknown contaminations in such biological
materials as well as chances of rejections. In the past 18 years it has been proven with all the latest scientific
parameters for their safety and efficacy.

Nichi-In Centre for Regenerative Medicine (NCRM)`s role in bridging the
gap between India and Japan:

NCRM has got technical collaborations with several Japanese institutes who
have strong research and development background and Indian hospitals who
have very good clinical skills. The major aim of NCRM is to develop
clinically usable stem cells, progenitor cells and cells with regenerative
capability, which are the backbone of Regenerative Medicine and to
standardize protocols of application of the same in clinical treatment
with such bilateral partnerships,. In this matter, NCRM`s core strength
has been several synthetic cell substrates such as Thermogelation polymer,
Hydro Gels, Nano composite materials and Nano-surface coated cell culture
technology, all of them have been developed by various Japanese institutes
in the past two decades. Apart from Acute Liver Failure, NCRM has also
been involved in the Research of Corneal limbal stem cells with Sankara
Nethralaya, Chennai, Corneal endothelial cell precursors with Joseph eye
hospital, Trichy and Retinal Stem Cells with Aditya Jyot Eye Hospital,
Mumbai
